hey everyone! I’m new to OpenGL, but have downloaded some sample projects to create an child window and display OpenGL using MFC, so I know it can be done and am fairly convinced I can do it. What I need, however, requires that I have two different OpenGL child windows running, one a simple 2D window displaying a mock up of aircraft display (text and buttons basically) and another displaying a fairly hefty 3D visualization. When I’ve tried to use these sample projects to implement two of the same openGL child windows, only one of them will animate, the other sits there doing nothing after originally being drawn. If I put another window in front of that window, and then go back to it, the second static image has disappeared, and only the first one is there, still animated. When I move the window the second static image comes back, but still doesn’t rotate. If I disable the first child window in the code and leave only the second one, then it animates fine. If anyone can give me any advice on having two different openGL processes display and update in one MFC window, that would be rad! domus
